Description

The Large Enriched Germanium Experiment for Neutrinoless ββ decay (LEGEND) searches for 0νββ in the 76Ge isotope.
A discovery would reveal the Majorana nature of neutrinos and prove lepton number non-conservation.
The proposed LEGEND-1000 phase consists of 1000 kg of enriched (>90%) Germanium detectors immersed in underground-sourced liquid argon, located at the underground facility LNGS in Italy.
For 10 years of the live-time the experiment aims to achieve a 3σ discovery sensitivity for the half-live of the 0νββ decay in Ge76 of at least 10^18 years.
